I use the scope display to set correct audio levels.
true, some tool for level setting is needed. I was successful using
arecord -D <device> -V stereo -f S16_LE -c 2 -r 48000 /dev/null
to display the received level and
AUDIODEV=<device> play -n synth sine 1000 gain 0
to send a reference sine to output.
Given, that the level has to be set external to soundmodem (physical
knobs or alsamixer) I believe measuring the levels externally as well is
not a too bad idea. What do you think?
On the other hand I might consider (re) writing some level setting helpers if you can give me detailed instructions of how you think this should work. I was not really satisfied with the graphics present in the GTK2 version of soundmodem.
I believe the best approach would be to use the besselnull method, but then you will need a different receiver since a FM receiver cannot be used for this method.
